Application filezl 11111215, 1906. Beriallio. 321.889.

To all whom it may concern: Be it known that I, WILLIAM B. OLIVER, oLSharon Hill, in the county of Delaware and State of Pennsylvan have invented certain new and useful Improvev Supp'orts, whereof the following is a specifica; tion, reference being had to the accompanying drawings.

My invention relates to a support, pivot .1113." mounted and sobalanced by means of se1f-contained spring devices, as to be capable of. rcinainingin a state of equilibrium when placed in any of the positions whichare within the range of its pivetai adjustment. The most extended use of supports of this, general character at the present time, is as an adjunct to, 'ofcarfier for, the ordinary desk telephone instrument. V g

This organization, as a. whole, involves-"the useoi somewhat cumbersome parts; and one obj ect of the pres .entinvention is to'sir nplity the structure by the elimination of certain relatively unimportant features, thus ,direc tly combining the transmitter casing and the receiyer with the self-balancingsupport, while at.the

same time permitting the use of the transmitting and receiving elements, in' the form commercially employ'ed' in the desk in'struin'nfs i'eferred to.

Another object of my invention is to advantageously modify the self-contained balancing elements, dispensing with some of the features heretofore employed for obtaining the differential action thereof. v Another objeiit of my invention is to so organizes.

'base and a self-balancing standard whose foot is carried by said base, as to permit the base to be attached either to a horizontal or 'to a vertical surface, and the standard to be mounted thereon in any one of'a great number of positions. p

Mariy ofthese features inayobviously be made'available broadly in this general class of supports, and hence are notto be considered as restricted to the particular form now indicated, as preferable for the entire organiration. i Iii. the accompanying drawings, Figure I, is a view, partly in side elevation and partly in a vertical axial section, of the support, and the telephone elements combined therewith, showing the foot of the support,

but not the base on which said foot is preferably mount- I .ed. Fig. II, is a view in vertical axial section through the upper portionof the support, the plane of section spring. Fig. V, is a front view of the upper end of the support, showing the transmitter casing, the main receiver hook, and the auxiliary receiver hook. Fig. VI,

' 'is a similarfm'iitview of the lower. end of the support and its foot. Fig. VII, is aview of the base and the;

foot of the support, shown in side elevation, the hase 5 5 being indicated as applied to a vertical wall. Fig.

under these conditions of mounting. Fig. IX, is an end: elevation of the coupling piece, the direction of view being toward the right in Fig. VIII. Fig. X,,is an end elevation of the base, showing it as applied to a, verticalwall, but in a direction at right angles to that shown in Fig. VII. Fig. XI, is a view, in side elevation, of the foot and standard of a modified form of the 7 device, adapted to be used with a special type of trans I mitter casing, which permits a relatively smaller amount of overhang at the top of the support than is characteristic of the type shown in Fig. I. Fig. 26111, is a view, in side elevation, of the foot of said modified form together with the base, which in thisinstance, is shown as applied to a vertical wall. v

The standard, or support properpis of substantially the same general organization in all the figures, and terminates at its lower end in a foot, which is adapted to be pivotally mounted, mediately, or immediately, upon a separable piece, which I ternr the base. Hence, I will preface the description of the standard itself bydescription of the base and the adjunctive coupling piecewhich permits adjustment in any one ofseveral positions.

iently be inclosed." A raised arm 3, projectsbeyond the attaching face and terminates ina cylindrical head 4. A central pin 5, projects from the face of said head,

- and is provided at its outer extremity with a threaded Thebase (see Figs. VII, viii, and X), comprise plate I, having preferably a hollow raised back, forming a chamber 2, in which the induction coils may convencavity 6, whose purpose will be stated hereafter. A

circumferential groove 8, (shown in dottedlines in Figs. VII, and VIII), isl formed around said pin about midway of length, and a pair of diametrical lugs 9, 9,

' are formed on the face of the head 4, extending outward from the pin 5, to the periphery of the face, Said lugs are preferably beveled as indicated. A washer 10,-h av ing recesses 11, corresponding in depth to the height of the lugs 9, fits snugly uponthe face of the head 4, and is provided on its upperside with a stop or projection 12. The lower end portion 13, of the standard (which I term the foot), is'iornied with a socket adapted to receive the pin 5, and a lateral set screw 14, is mounted in the foot in proper relation to engage in the groove 8, of the pin 5,

so that when the foot of the standard is mounted in position, with thewasher 10, intervening betweenit and the head 4, the"parts are secured together, but are rota table upon the 5,throughout a comparatively large cured against a vertical surface, and with its ,pin5, per- I pendicular (as shown in Fig. VII), the foot is mounted directly upon the pin 5. When, however, the base is secured to a horizontal surface (as shown in Fig. VIII), or with its pin 5, standing in a horizontal position, (as

shown in Fig, X), it is necessary, inorder to preserve I,

the vertical position oi the foot 13, to interpose a coupling piece. This coupling piece is shown in Figs. VIII, an d IX, and comprises two members '15, and 16, ar-

ranged at'a right angle to one another, and corresponding in diameter to the head 4, oithc base. The region of union between thernembers 1'5, and 16, is preferably of rounded configuratioinas indicated, at 20, in FigQ VIII 7 Themernberliih'as a socket 7,;adapted to re-.

ceive the pin 5," ofthe base, the opening of said socket extendingthrough the union 20.

U pen the end face of the member 15, audadjacent to the opening of thesoeket 7,, are four radial slots 21, arranged in quadrant ,jlp'ositions, and corresponding in cross-section with theradial lugs 9,, upon the base. The

member-1'6, has a centralgpin 17, with a, circumferential groove 18, and diameftrical lugs19, 19. f :Ihe ,coupling piece can be inountedyuponthe pin 5, oflthe base, in any of the quadrant positions which permit the registry of the slots 21, withthe lugs 9, and can then be secured rigidly by means of the screw22,iwhich eng threaded cavity 16, of the pin5, It will, that when the coupling piece, is mounted in the position shown in Fig. VIH the member 16, with its pin 17, stands vertically and reproducesthe same general conditions for mounting the standard, as existed when the base was arranged upon a vertical surface, as

shown in Fig. VII. Hence the foot 13, of the standard will fit vertically upon'said pin 17, and can be rota- 40 tively secured thereto by means of the set screw H,

which now engages in the groove 18.

I will now describe the preferred organization of the standard and balancing mechanism. The standard comprises afoot, two telescoping tubular parts, (which I term the upperand lower stems), and an overhanging topp'ortion; The foot 13, carries'a segrnental cam piece 24, stoutly supported by means of a web 25 The upper end oi the foot iscutaway on eachside (see Y1), so as to form-flat bearing faces 26, 26, adapted to receive the bifurcated and rearwardly curved ends 27, 27, of

the lowerstein 28, 'whichaie rotatahly secured 'to the foot by meons'of a pivot 29. Said pivotis provided with a thumb nut and spring lock washer 3,0, in orderto permit a' regulatedlirictional engagement with the 515 race and to assist if necessarythe devices for maintaining equilibrium: A stop 23, limits. the

rearward movemennof the standard. [Said balancing I ldevices a reforganir ed asfollows';--The lower stem 28, which ispreierably tubulanas shown, carries a coiled spring 31 w l1ose upper end abuts against the ringnut,

32, (see Fig, IV), which is mounted upon the threaded H tubular piece 34; The upper end of the piece 34, is slotted and the portions 35, correspond ing with the" extent of the slots are turned outwards intoa horizontal 6 5' position; These portions 35, engage beneath theoverhanging flange 37, formed on the upper en d of the lower stem 28, so that the tubular piece 34, is rotatablysupported against upward thrust. The ring nut 32 carries 'a pin 38, which engages in a vertical slot 40, formed in the lower stem 28, and preferably extending through out substantially the greater portion of its length.

The lower end of the spring 31, exerts pressure against the bearing block or shoe 42, which slides freely within the lower stem 28. Holes 43, are formed through said shoe 42, to permit the passage of the telephone wires, which extend down through the standard and emerge at the lowerend' thereoi, as will be described hereafter I helower surface oi the shoe 42, is adapted indicated in dotted lines in Fi 11.

Thepurposeoi giving an inclination to'the slot 51,

lation to theaxisof the standard and also of employing .clination oi the standard, as awhole, to the perpendicube of any of the well known typ'cs, the spring 58, having ally and upwardly hook. I il wi of the P rts BL rwnjri'the various figures is that whichoccunuwhen the receiver 60, isilifted from the book 53, an s ks o t h k; slot 51'; 'Under thsef M against the shank 52,.of the receiver etpoqition iii 'the stantial equilibrium may be maintained in any position of the standard, as will readily bc understood. Theupper stem 46, also preferably tubular, is fitted telescopically upon the lower stem, being slotted, as indicated at gitudinal adjustment with relation to each other. The

parts, secured together at the region-.50; The upper,

contain in. its interior the circuit wires and contact pieces characteristic of any prdinary desk telephone:

I Near the upper end of the upper stem 46, an inclined slot 51, is formed to permit the u'pand down I plate 55-, which affords a. bearing surface parallel to the inclination of the slot 51. The receiver hook 53, =-is by ineans of a swivel conand pivoting the shank upon an axis inclined with rea a swivel mounting for the hook 53, is to insure the proper I action of gravity upon the parts, irrespective of the in larJ As before stated, the contact'picccs'et cetera, may

e 58;liu: thrown the bends, prjessesthe stud 61 against the switch 62, and thus establishes the circuit between said switch member and the line conductor 65. When, however, the receiyei it}, is e A the'heek es, skectiesei grew ity causes the latter to descend the incline of the slot 51,

and the shank 52, of the hook forces; the spring-58, inthe corresponding directionpso that the pressure of the stud 61,upo n the switch member 62, is relieved and the latter springs out of contact with the member 65."

' upon which the shank 52, is pivoted, and the freedom allowed by the inclined slot, the proper gravitative effect ofthe receiver is always insured.

The upper end 68, oi the standard is reduced in size and bent outwardly so as to form an overhanging sup port for the telephone transmitter casing 70. In the in-' stance shown, this casing is oithe ordinary type found in desk instruments and has a rearwardly projecting part 71, which is pivotally connected at 72, .to a curved arm 73. Said arm 73, terminates inQ-a cylindrical boss 74, which is pivoted upon a vertical axis by-means of a screw pin 75, secured to a downwardly depending piece I 76, which is "pendulently secured 'to the overhanging shpport 68, by means of the horizontal pivot fi). It will thus be seen that the connection between the trans- 3Q mitter casing 70, and the support 68, is of such a character as to permit the pendulum-wise swing of the casing, which maintains it in its proper relation in all the various positions of the support with reference to the vertical, and also' that the transmitter casing and mouth piece are revoluble upon a vertical axis, thus greatly adding to the convenience of the device. An auxiliary receiver hook 79 .proj ects laterally from the part 7 4, so as to bpth rotate and swing therewith, the purpose oi such auxiliary hook being to permit the hanging up of the re- 4Q ceiver when it has been removedfrom its spring actuated hook 53, and during the interval when it may be desired to maintain the talking circuit, although the I telephone itself is temporarily not in actual use.

. In Fig. 1, in the solid lines, the receiver is shown as ;4 5 supported upon said auxiliary hook 79, but in tho those which are due to the different organization of the transmitter. casing. Instead of utilizing the transmit- ,ter casing of the ordinary desk instrument, the casing 80, in this instance, is of a special type, which has no rearwardly projecting point of support, but is provided on, its upper side with a verticalprojection 81, rotatively secured within a coupling .82, which is pendulently supported by the horizontal pivot 83, connected to the overhanging top 84, of the self-balancing support indicated comprehensively at The auxiliary 00 receiver book 86, is in this instance. attached to the lower side of the casing 80, by means of the downwardly depending stud 87. By this arrangement. as in the other case, the transmitter (using with its mouih piece and the auxiliary receiver hook, me rolntivciy mounted upona vertical axis, and also swing penduhim-wise upon the pivot 83. The general organization of the self-balancing support may be the same as that .just described but it will be noted that the overhanging tsp there'ei oi lateral extent than in the. type shown in Fig. I, this modification being permitted by reason of the absence of projecting members at the rear of the transmitter casing. The difference in the center of gravity due to the diminished amount of overhang must of course be met by a corresponding modification of the cam surface 86, mounted upon the foot 88. Furthermore, the lower extremity of the standard, instead of being provided with the rearwardly projecting curved parts shown in Fig. I, may be straight as indicated at 89, so that the axis of the standard when in a vertical position, is coincident with the axis of the foot, instead of being out of line therewith, as in the type shown in Fig. I.

In both forms of organization it will be noted that the auxiliary receiver hook is at the right hand of the month piece as faced by the user, and that it maintains its definite position with relation to the mouth piece regardless of the swinging or rotating movement of the transmitter casing, thus avoiding confusion withv the normal or regular receiver hook which is usually lo-- cated at the le eloi the mouth piece. In both types of supports, the circuit wires lead down' through the standard and pass through the openings 43, in the shoe 42, emerging at the foot and ,being thence led into the base-piece, through the opening 90, for. connections with the induction coils, not shown. I

To avoid prolixity-in my claims I use the term selfbalancing support, as meaning a pivotally mounted structure of the'kind described, controlled by selfcontained spring devices, which together with the friction of the moving parts maintain the structure and the elements carried thereby practically in a state of equilibrium as against the action of gravity in any of the various positions which the standard may assume.
